Earthquakes in Chile — March 2025

45 earthquakes were recorded in Chile during March 2025, an average of 1.5 per day.

43 reached magnitude 4 or above and 6 reached magnitude 5 or above. The average focal depth was 93 km.

The month's largest event in Chile was a magnitude 6.1 earthquake near San Pedro de Atacama, Chile on 06 March 2025 at 16:21 UTC. A magnitude 6.1 earthquake radiates roughly 21,301 tons of TNT equivalent in seismic energy.

That is well above the Chile monthly average of 33 events over the period we cover — an unusually active month, and up from the 35 recorded the previous month.

38% of events here are shallow (under 70 km), 62% intermediate (70–300 km) and 0% deep-focus (over 300 km). A substantial share of intermediate-depth events points to a subducting slab beneath the region rather than purely crustal faulting.

By band, the catalogue holds 2 in the magnitude 3 range, 37 in the magnitude 4 range, 5 in the magnitude 5 range, 1 in the magnitude 6 range.

Activity peaked on 14 March, when 3 events were recorded.

The month's largest events were M6.1 near San Pedro de Atacama, Chile on 06 March at 94 km; M5.4 near La Tirana, Chile on 25 March at 100 km; M5.3 near Coquimbo, Chile on 18 March at 64 km.

That is 34% above the 33 events Chile averages per month across the 21 months on record.
